The recuperatiOn of soils by natures
means is not swift process. The for
nation of the soil originally required
ages of time. First the rock must be
broken down and disintegrated. Then
plants must gradually absorb such por-
tons as are soluble in water or else
present in the atmosphere. and the
plants by decay are reduced to humus.
Then the real work of soil-building
commences in earnest. So important
is this humus in the soil that the
average soil from which two inches in
thickness il removed remains for long
period infertile. unless specially treated.
The reason of this is. the humus in
soils, unless mixed artificially with the
under soil, remains next the surface.
The principal Offices Of humus are. it
absorbs and retains moisture, furnishes
carbon and the mineral elements in de-
cayed vegetation in . soluble state to
plants. and especially is the prime
agent in carrying ON chemical trans
formations in the soil, evolving.
through heat and moisture. carbon,
oxygen and hydrogen. and also nitrogen
in soluble form for the use Of plants.
Hence the value Of grass and forage
plants that may be fed to animals or
turned under. enriching the soil by their
constituents, or by being plowed under.
Thus in all long cultivated soils the
humus is intimately mixed with the soil
to the depth Of blowing. while in soils
never plowed. IS in woodland. the
humus. until thoroughly decayed. re-
mains rs the top layer Of the soil to .
greater or less depth, according to tho
amount annually deposited.
Very few farms make sufficient ma
nure from the animals fed to properly
manure the soil. unless stocked to its
full capacity, and then only when great
care is taken to save and make manure
with all its constituents intact This
is laborious work. and costly as well.
Hence the utility and economy Of plow-
ing under sward and other green crops.
as . part Of the rotation Of the soil. BY
this means the whole value of the crop
is returned to the soil. while in the
feeding of animals only minor part is
SO returned. Hence. again. as stated
lately by us. the value of covered fall
lows, rather than of naked ones. when
q fallow is considered absolutely neces-
sary.
The more advanced farmers Of the
country are adverse to allowing land to
be naked at all. except during the time
q crop is springing up. Whom SO al

sun bakes the land. and aside from the
